2.3 Connection of the sauna heater to the mains

The sauna heater must be connected to the mains by a qualified electrician and in compliance with current regulations.
The sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66) cables or a
corresponding type. Other output cables (signal lamp, electric heating toggle) must also adhere to these
recommendations. Do not use PVC insulated cable as a connection cable for the sauna heater.
A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control current fuse, the
diameter of all cables must be the same, i.e. in accordance with the front fuse.
The connecting box on the sauna wall should be located within the minimum safety clearance specified for the sauna
heater. The maximum height for the connection box is 500 mm from the floor. See page 8. Locating the connecting box for
the connection cable in the sauna room
If the connection box is located at over 500mm distance from the heater, the maximum height is 1000mm from the floor.
Table 2. Kables and fuses for heater 1106 – XX (SKLF / Octa)
NOTE: Controlling the lights in the sauna with the circuit board is only possible with resistive loads (incandescent light
bulbs). The circuit board relay cannot withstand capacitive loads (switched-mode power supply units). If the lighting fixtures
in the sauna have transformers, for example LED or halogen lamps, the stove circuit board's relay control must be fitted
with a separate relay or contactor for controlling the lights.
Sauna heater insulation resistance:
The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leakage currents.
The moisture will be gone after a few heating sessions. Do not connect the heater power supply through a ground fault
interrupter.
However, adhere to the effective electrical safety regulation when installing the sauna heater.

2.4 Electric heating toggle

The electric heating toggle applies to homes with an electric heating system.
The contactor case has connections (marked N - 55) for controlling the electric heating toggle. Connectors N – 55 and the
heating elements are simultaneously live (230V). For more specific instructions, please refer to the operating manual of
the WE 40 contactor case.

2.5 Using the contactor case

The contactor case is intended to be installed outside the sauna
installation. A connection box must be installed in the sauna room with a semi-fixed installation on the sauna heater.
For more specific instructions, please refer to the operating manual of the WE 40 contactor case.

2.6 Door switch

The door switch refers to the switch on the sauna door. This switch complies with regulations. Public and private saunas
where the heater can be switched on from outside the sauna must have a door switch, e.g. by using the control panel, an
On/Off button or a similar method.
For more specific instructions, please refer to the operating manual of the WE 40 contactor case.

2.7 Safety railing

If a guard rail is to be built around the heater, the rail's safety distances must be the minimum distances specified in Table
1 on page 5. The guard rail must be a single rail, not a wall.
